실험 절차
N-nicotinoyl-3-methoxytyramine was prepared by following the procedure used for the preparation of compound 7. The isolated crude amide was quaternized directly with methyl iodide following the method used for the preparation of compound 6a. Crystallization from methanol gave a yellow crystalline compound, m.p. 192°-194° C. with overall yield of 84%, calculated on the basis of 3-methoxytyramine starting material. NMR (D2O) closely similar to that of 6a except for the singlet at δ 3.66 for OCH3.
